Update on Cialis® Rx-to-OTC Switch Actual Use Trial

Paris. May 30, 2022. The U.S. Food and Drug Administration has informed Sanofi that its planned Actual Use Trial (AUT) to support the Rx-to-OTC switch for Cialis® (tadalafil) has been placed on clinical hold due to matters surrounding the protocol design. Sanofi’s AUT has not yet recruited any patients. Sanofi continues to work with FDA to move the Cialis® program forward and will engage the Agency in upcoming meetings as we determine next steps.

About Cialis

Cialis is not for women or children. It is important to note that Cialis is not to be taken with medicines called "nitrates" such as isosorbide dinitrate or isosorbide mononitrate which are often prescribed for chest pain; or with recreational drugs called "poppers" like amyl or butyl nitrite, as the combination may cause an unsafe drop in blood pressure; or if allergic to Cialis or Adcirca® (tadalafil), or any of its ingredients. Anyone who experiences any symptoms of an allergic reaction, such as rash, hives, swelling of the lips, tongue or throat, or difficulty breathing or swallowing, should call a healthcare provider or get help right away.
